1.737, sitting in the front row of economy class is definitely the best. The back row is bumpy, and the front cabin will not be too bumpy when it encounters airflow. Take the baby to the first row of economy class, with a large front row. Otherwise, you'd better sit in the aisle.

There are two kinds of 737-700 of China Southern Airlines. When away from the wing engine, the noise is low, and 42 rows of wings will block part of the line of sight and affect the overall scenery. But I prefer to look at the position of the wings. It's good to have a reference for the scenery. If you want to see the whole scenery, I recommend the first row of economy class, which has more space and less noise, depending on which 737-700 you are in China Southern Airlines.
